| description | Direct catalytic methanation of CO<sub>2</sub> (from CO<sub>2</sub>/CH<sub>4</sub> biogas mixture) to produce biomethane was conducted in a pilot demonstration plant. In the demonstration project (MeGa-StoRE), a biogas desulfurization process and thermochemical methanation of biogas using hydrogen produced by water electrolysis were carried out at a fully operational biogas plant in Denmark. The main objective of this part of the project was to design and develop a reactor system for catalytic conversion of CO<sub>2</sub> in biogas to methane and feed biomethane directly to the existing natural gas grid. A process was developed in a portable container with a 10 Nm<sup>3</sup>/h of biogas conversion capacity. A test campaign was run at a biogas plant for more than 6 months, and long-time operation revealed a stable steady-state conversion of more than 90% CO<sub>2</sub> conversion to methane. A detailed catalytic study was performed to investigate the high activity and stability of the applied catalyst. |
